English (Bedfordshire): variant of Missenden, a habitational name from Great or Little Missenden (Buckinghamshire). The placename may derive from Old English myssen ‘growing with mysse’ (a derivative of the plant name mysse, the exact sense of which is unknown) + denu ‘valley’. Alternatively, the initial element may be a lost river name Mysse (genitive Myssan), probably an early name for the river Misbourne.
